WEED-CUTTER.

Specification of Letters Patent.

Patented Dec. i6, i913.

Application filed March 25, 1912. Serial No. 685,928.

To @ZZ 107mm 15 may concern Be it known that I, CLIFFORD E. JONES, a citizen of the United States, and a resident of Eightmile, in the county of Morrow and State of Oregon, have invented certain new and useful Improvements in feed-Cutters, of which the following is a specification, reference being had to the accompanying drawings.

This invention has relation to certain new and useful improvements in cutters of that class which are dragged over the field and are especially adapted to be used in fallow ground; and the object of my invention is to provide a cutter of this general character of a simple and inexpensive nature and of a compact and durable construction, arranged so that a plurality of oppositely directed drag knives are drawn through the eld to loosen the soil and cut the weeds as well.

With these and other objects in viewa the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the speciic structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views; Figure 1a shows a top view of a two frame weed cutter embodying my invention. Fig. 2, shows a rear view. Fig. 3, is an end view.

In my present invention I provide a weed cutter especially adapted to be used in the cultivation of fallow ground, that is, ground left unseeded for a time. With my invention such ground cannot only be kept free of weeds, but in removing the weeds the top of the soil is cultivated and dressed, in that the cut weeds form a mulch so that by the time of planting the ground will be in the best possible condition.

In carrying out the aim of my invention I employ a frame comprising a front bar 1, a rear bar 2, and a plurality of sills 3, secured to the members 1 and Q, in parallel spaced relation. The sills 3, are slightly mortised as shown in Fig. 3, to receive the members 1 and 2, these members being secured to the upper edges of the sills by means of suitable bolts a. 'Io further add rigidity to the frame, I employ a cross bar 4, which is also secured by means of suitable bolts a, this bar being positioned between the bars 1 and 2. Secured to opposite sides of each sill 3, are the cutting members which are in the form of knives made of flat strap metal, preferably of a good quality of tool steel,

As shown in Fig. 8, each knife comprises an apertured securing stem 5, through the apertures of which extend the securing bolts 6. Each stem is obliquely secured to one vertical face of the sill. The blades or cutting portions of each knife include a crooked or curved portion 7, from which the blade proper is continued laterally and rearwardly, as will be understood in referring to Each blade is wedge-shaped in cross section and is tilted so that the forward cutting edge 10, is lower than the rear edge 12, of the knife. As shown in Figs. 2 and 8, the cutting edges of all of the knives end and extend in a common plane.

In the drawings each sill 3, is shown as giving support to two drag knives and these knives are so positioned that their curved or crooked portions 7, extend below the lower edge of the sill to which the knife is secured, the blade 9 extending cbliquely, laterally and rearwardly. rlhe knives upon each sill extend in opposite directions, this requiring two kinds of knives which for convenience I call right handed and left handed knives. The knives extend rearward of the line of advance, as will be understood in referring to Fig. 1.

For the sake of convenience, I employ a lead bar 15, to which two or more of the drag frames are secured. As shown, I provide the two end sills of each frame with a clevis 16, held by means of a bolt 17, each clevis carrying a link 18, engaging an eyebolt 19, secured to the lead bar 15, this construction being shown in Fig. 1. The frames in turn are shackled together at their rear inner ends by means of a chain section 20 engaging the hook plates 21, each frame having such a hook plate as shown. These hook plates are held in position by the bolts a, securing the rear bars to the end sills 3.

As shown in Fig. 2, the knives are made to extend out-ward a distance sufficient so that the ground is cultivated the entire distance between the points of the outer edge knives. r[he links 18 permit each frame to swing from side to side within certain limits, so that each frame is yieldingly held to the ture of my invention, asis the arrangement of securing the knives tothe'sills.

In Fig. l, I have shown a 3 horse evenerv A, secured to the lead bar l5, by means of the connecting rods 25, secured totheeyebolts 2G.

A'weed cutter constructed according to "my invention is simple and inexpensive and both durable and eiiicient in operation.

I-Iaving thus described my'said invention, what I claim as new 'and desire to sec-tireby United States Letters Patent is:A

l. A weed cutter comprising` a frame consisting of front'and rear cross bars and a plurality of `sills secured to said'bars and spaced apart, and a series of knives bolted to said sills upon opposite sides thereof,` each knife extending underneaththe sill and having its blade in a horizontal plane at the opposite side of the sill y from its point of attachm'ent to said sill whereby a complete unbroken cutting edge is presented across the entire weed cutter.

2. A Weed cutter comprising a plurality of frames flexibly connected to a leadbar and permitted toswi'ng freely within certain Alimits laterally, sills carried by said frames and extending in the vline of draft, knives connected to said-sills upon oppositesides thereof, said knives each extending underneath the sill 'and' projectingrearwardly and vbackwardly therefrom, vthe l"knives ofieach CLIFFORD E. JONES. I/Vitnesses C. II. RHEA, EDWIN M. HAWLEY.
